Attribute-based proxy signature scheme for unmanned aerial vehicle networks by Lei HE, Jianfeng MA, Dawei WEI

“…It is necessary to use digital signature scheme to protect integrity and authentication of commands sent by command agencies to unmanned aerial vehicle (UAV) in the UAV networks.Moreover, the signature scheme should ensure UAV can receive signature in time and protect privacy of signers.Therefore, an attribute-based proxy signature scheme for UAV networks was proposed and its security was analyzed.The proposed signature scheme has existential unforgeability under selective-attribute and chosen message attacks, and privacy of signers is protected.Its efficiency was analyzed in terms of computation costs and communication costs, and compared with other related signature schemes.The results indicate the proposed signature scheme has less computation costs when its communication costs are at the same level with other signature schemes.…”

Symbol timing recovery algorithm based on ordered statistic of maximum mean power timing for WBAN by HIYu C, HENLan C, VChao L

“…The symbol timing algorithm based on maximum mean power timing is independent of carrier phase offset,and has the property of capturing timing information fast,which meets the demand of wireless body area networks (WBAN).According to IEEE 802.15.6 standard,the ordered statistic of maximum mean power timing was used to reduce the computational complexity in the symbol timing process.The theoretical analysis and simulation results shows that the proposed algorithm can achieve symbol timing within 32 symbols and reduce the computational complexity by ninety percent at most compared to the original maximum mean power algorithm.The fast synchronization and car-rier-independence property of the proposed algorithm can also make room for carrier-offset recovery and frame synchro-nization.…”

Recognition method of digital modulation signals over non-Gaussian noise in cognitive radio by Ming-qian LIU, Bing-bing LI, Chao-feng CAO, Zhao LI

“…In cognitive radio system,the traditional methods of digital modulation signals recognition with Alpha stable distribution noise have the problems of poor performance and high computation complexity.A novel recognition method based on correlation coefficient of fractional lower order cyclic spectrum was proposed to solve this problem.The method extracts the recognition characteristic parameters which are five correlation coefficients of the fractional lower order cyclic spectrum’s section and frequency spectrum’s section and projection planes of both,and then decision tree was used as a classifier to achieve digital modulation signals recognition.Simulation results show that the proposed method not only has higher recognition rates and better robustness but also has lower computation complexity in an Alpha stable distribution noise environment,which is more suitable for cognitive radio system.…”

RFID security authentication scheme based on Montgomery-form elliptic curve cryptography by Wumei ZHANG

“…For the issues that the existing RFID security authentication scheme based on elliptic curve cryptography （ECC）can not meet the requirements of mutual authentication,privacy protection and forward security,a RFID security authentication scheme based on Montgomery-form elliptic curve cryptography was proposed.This scheme uses the Montgomery elliptic curve to reduce the amount of computation,and to provide mutual authentication between the label and the server,and anonymity and forward security.The analysis showed that the scheme could resist replay attack,tag camouflage attack,server cheat attack,DoS attack,position tracking attack and clone attack.Compared with the existing schemes,the proposed scheme provides high security performance under low memory,computation and communication requirements,and it can meet the security requirements of the RFID system.…”

Distributed locating algorithm for wireless sensor networks-MDS-MAP（D） by MA Zhen, LIU Yun, SHEN Bo

“…A new distributed locating algorithm MDS-MAP（D） was proposed,which attempted to improve the perform-ance of node localization in wireless sensor networks.The process of the computation about node relative coordinates and the aggregation from local network to global network are introduced explicitly.Further,the analyses to computational complexity and the simulations of the algorithm are also present.MDS-MAP（D）,which is based on node clustering mechanism and uses connectivity of nodes to estimate the coordinates of nodes,reduces the complexity and energy con-sumption of node localization on the absence of distance measurement with high precision.The simulation and analysis results indicate that the complexity of node localization algorithm falls to O（Nm 2）,m < N from O（N 3） and the accu-racy is improved 1%～3%.…”

“…In order to effectically cancel the intercarrier interference（ICI） in the OFDM（orthogonal frequency-division multiplexing） systems,a novel iterative detection algorithm was proposed based on parallel interference cancellation.With the principle of maximize the minimum signal-to-interference and noise power ratio,the received signal was proc-essed by decision,reconstruction and ICI cancellation,iterative algorithm based on ICI cancellation was set up,the flow chart on signal detection was given.On the basis of analysis on time-varying channel,the influence of the normalized Doppler frequency offset on the system performance was investigated.Computer simulation results were presented.Simulation results show that the proposed scheme can improve the system performance significantly by using of the time diversity of time varying channel.The computational complexity can be reduced form O（N 3） toO（N）.…”
